I havnt gotten that far but im all about baller on a budget lol. And ive seen the Megasquirt things and that arnt exactly cheap. So I dont know the electronic s like you guys do yet but what about this option. .

Use SAFC2 and just install a 2 Bar GM MAP sensor found at pretty much any yard that has a supercharged GM vehicle. Theres many to choose from. Or if ya want I know there are online sources where you can get up to 4 bar map sensors for not much more. It provides a 0-5v read out like the tps so you just use that as your tps input on the safc and bam safc is then adjusting per boost not throttle position. Theres a bit more too it but I know some Miata guys have used this with some success

Re: Using SAFC2 And A 2 Bar Map Sensor

You don't have to use a GM MAP. But they are very available. Buggs here on the forum used a 3bar rx7 map. It is by far the best way to go over the voltage from the tps. He dyno'd at like 220ish with 8psi on a vf10/vf12 hybrid and an NA BP, with a slipping clutch.
